Here's another item from the eBay pig in a poke I got a while ago. I was going through the V-nickels, sorting out some of the more unfortunate ones for another thread, when I came across this beauty: I had to stare at it for quite a long time, with different lighting and magnification, before I could be sure that this "blob on the back" wasn't going to be the same Disappointment that I've found on all the other 1912-blob V-nicks from various batches. Close-up, though, it's pretty unambiguous: So, is there anything to be done about this blotchy-pink corrosion? I'm not planning on doing anything rash to this coin, certainly not hitting it with vinegar or the like, but I can imagine it being made a bit more presentable. Any ideas/experience? (In this shape, I don't think it's worth shipping to NCS; I imagine there's a market for it on eBay as-is, anyhow.) Thanks to CTDirtFisher for his recent post of an even better find, which got me motivated to go ahead and post this one as well. You win this round, CTDirtFisher...
That's pretty heavy, first try a 24 hour soak in distilled water. Beyond that, VC might help it some, but nickel corrosion mixed with verdigris is a very tough nut to crack. It looks like it already had an old, acid cleaning which is why it's red and blotchy.
